may concern:

Be it known that I, DANIEL E. ANrHoNY, a

citizen of the United States,

in the county of Plymouth and State of ron,

Iowa, have invented residing at Akcertain new and useful Improvements in Corn-Harvesters, of which the following is a specification.

invention relates to corn-harvesters,'

and more especially to that class of corn-harvesters illustrated in me January 1, 1901; and invention consists in certain details of 665,301, granted to Letters Patent No.

d for use either singly or said Letters Patent or otherwise, as fully set forth hereinafter and as illustrated in the accompanymg drawings, in which Figure 1 1s a side elevation of a corn-har vester embodying my improvement; Fig. 2, a

viewlooking from the front, showing the gatherers and adjuncts.

Figs. 3 and 4 are views illustrating modified forms of the rotary lifter. Fig.

5 is a plan view of the machine;

Fig. 6, a section on the line 6 6, Fig. 5; Fig. 7, an elevation on the line 7 7, Fig. 5; Fig. 8, an enlarged section on the line 8 8, Fig. 1 Fig. 9, a still larger section illustrating the action of the snapping-rolls.

Fig. 10 is an enlarged sec tion showing the lower bearing of one of the rolls. Figjll is a perspective view of the The main supportin ers G H, elevating-belt and the general arframe A, the gatherrangement of the parts and the driving means for the snapping-rolls J K may be of any suitable construction and will be so well understood from the said Letters Patent the same here in description to the As in my snapping-rolls J K ar upward, and the roll 30 extending spirall 'havin a more rapid that t e groove or channel into which the.

aforesaid Letters illustration in my aforethat I will not describe detail, but will confine my features of improvement.

Patent, the e inclined backward and K is a shaft having ribs v around the same, but

twist toward the top, so

stalk passes is vertical ,or nearly vertical at the lower ends of the rolls and gradually inclines forward toward 'rlbs of the roll J are reversely inclined to the upper ends. The

those of the roll K without any intervening cylindrical surface. Each rib 30 is wedgelike in cross-section-that is, the outer face y of the rib is inclined inward toward the direction in which the roll rotates, which is toward the rear of the machine, as illustrated in Figs. 8 and 9and as a result there is a tendency to force the ear forward in the direction of the arrow, Fig. 9,

face y and the face of the opposite roll against the butt of the ear. This result is further increased by forming a shoulder as at the heel or inner edge of the rib or at any point on the face of the rib, which shoulder will engage the stalk and tend to carry it backward while the ear is squeezed forward, hus facilitating the separation of the car from the stalk.

In order to act effectively to separate the ears according to the position which they oc cupy upon the stalks, which in some growths is much nearer to. the ground than in others, I construct one or both snapping-rolls so that it may be brought parallel to or at an angle to the other in such manner that the proximate parts may be at any desired position between the ends of the rolls. Thus, as shown in Fig. 1.3, the general outline of both rolls tapers from the center toward each end upon curved lines, and the rolls may be so set that,

as shown, the proximate parts at 'v v, where the snapping 18 to be effected, are about onethird the distance from the lower end, and this distance may be increased so as to bring the rolls closer together at any desired point between their ends corresponding to the average height of the majority of ears from the ground.

In Fig. 12 but one of the rolls is shown as reduced in diameter toward its en 1 1 the taper from each end of one of the rolls is conical. In Fig, 14 both rolls have a conical taper toward the lower ends, while in Fig. 15 bot-hrolls have a conical taper toward the upper end. It will be seen that in each construction the axis of one roll when shifted in respect to that of the other will shift the point or operating-section of, the roll to different de rees from the bottom ends.

The roll or rolls may be supported so as to be axially shifted in any desired manner. As shown in Fig. 11, the roll J is sup orted in fixed bearings, while the shaft of t 1e roll K turns in a step 2, having a slot 3 to receive a securing-bolt 4, that permits the step to be bv the pressure of the said In Fig swun or set to difierent positions laterally 1 and t en secured, and the upper end of the I I erally and abruptly at points near the ground,

and in order to secure this result I combine with one or both the gatherers a rotary lifter L, which may be conical, as shown in Fig. 2, or a truncated cone, as shown in Fig. 3, or hemispherical, as shown in Fig. 4, or of any other suitable form which will present a face having a greater inclination forward than that of the face of the gatherers. This lifter rotates freely about a shaft 12, extending outward from the gatherer and supported by a. bracket 13, so that the lifter can rotate freely by frictional contact with the bent stalk,.and, passing with a wedge-like action underneath the latter, will tend to throw it upward and inward so as to be brought eflectively under the action of the lifting or elevating chains 14.

n order to insure that the leaves and broken portions of the stalk shall be engaged by the rolls, I combine with the apparatus a blower N of any suitable character, and from this blower I extend conduits 16 17, the ends of which are so arranged as to project one or more blasts of air against the standing corn and toward the rolls. This air blast or blasts will blow the loose leaves and stalks against the rolls, so as to insure the latter biting the same. To prevent the obstruction of the lower bearings of the roll-shafts by earth, &c., I refer to make each step with an annular co lar or flange 47, ada ted to enter an annular groove 48 at the ower end of the rolls and surrounding the shaft thereof, and an oilcup 49 may communicate with the oilspace inside the rojection or collar 47, so as to thorou hly ubricate the step-bearin from which t e earth, &c., is thus exclude One of the gatherers G extends farther back than the other and is provided with an elevating-chain 19, and in order to support and push back the stalks at the opposite side I make use ofa push-bar 20, which is eccentric to a shaft 21, turning in bearings of the frame and driven from the fly-wheel shaft 38, constituting,1 as shown, a long crank of said shaft, whic as it is carried around and against the stalk, secures the desired result.

At one side of the machine is shown a plurality of pairs of husking-rolls P, which may be of any suitable character, but which, as

shown, are inclined downward toward the rear, and in order to open up the husks and loosen the same so that they will be grasped by the rolls I project an air-blast against and toward the upper part of the rolls-from a blower M of any suitable construction and in such manner as to meet the ears as they pass downward. The devices ordinarily employed act with a mechanical pressure to ress the ears against the rolls, and this ten s to hold the husks to the ears and prevent their separation; but the air-blast, as described, tends to open or loosen the husks and force them into engagement with the rolls, but without any mechanical ressure of the ears themselves against the ro ls.

Ordinarily the ears are thrown indiscriminately onto the husking-rolls and are apt to pass toward one side or the other, so that they are not evenly distributed and in many cases fall crosswise, so that they are not operated upon. To prevent this result, I make use of a distributer Q, which, as shown, is provided with parallel trou hs 25 25, having sides con-. verging toward t e open bottoms, in which are feedingbelts 26, provided with teeth. There is one of these troughs to each pair of huskin -rolls, and the troughs are inclined upward toward the upper ends of these rolls, and as the result if one trough is filled the ears tend to fall into the other trou h, and in any case tend to take a longitudinaI position, and are therefore fed longitudinally to the upper ends of the husking-rolls. Where it is not desired to feed the ears toward the huskingrolls, the troughs may be so arranged as to distribute the ears and arrange them longitudinally.

It will be seen that the roll K, which is carried by the swinging bracket 7, has a pinion 32 upon its shaft, which gears with a pinion 31 upon the fly-wheel shaft 38. As a result after the apparatus starts in operation the rotation of the fly-wheel in the direction of its arrow, carrying the pinion 31 in the said direction, tends to exert a thrust to swing the pinion 32, with its shaft and the bracket and the roll K, forward in the direction that the fly-wheel rotates, and this tends to open or separate the rolls to a certain extent, so that it takes less power to carry the stalks between the rolls than would otherwise be required, especially when there is a large bunch passing through at one time. This. tends to counteract the excessive pressure of the spring when there is such a large bunch operated upon.

While for the purpose of illustrating my invention I have shown certain features of construction, it will be evident that the construction may be varied without departing from my invention, and it will also be evident that while I have shown the various features above specified as assembled in a single aptoward said shoulder :10.

3. In a corn-harvester, a rotating snapping-roll having rigid spiral ribs with shoul ders :1; the faces of said ribs inclined inward toward said shoulders a; in the direction in which the roll revolves.

4. The combination in a corn-harvester, of

gatherers a pair of rotating rolls inclined ackward and upward and having'on their surfaces rigid spiral wedge-like ribs, the faces of the ribs on the adjacent sides of the rolls inclined in reverse directions.

5. The combination in a corn-harvester, of gatherers, ribbed snapping-rolls, one of decreasing diameter toward the end, and bearings ad ustable to permit the rolls to be set with their axes diverging, with the adjacent working parts at either end parallel.

. 6. The combination in a corn-harvester, of a pair of ribbed snapping-rolls one of increasing diameter toward the center, and movable bearings whereby the rolls are relatively adjustable to permit them to be set with their adjacent working parts parallel at either end.

7. The combination with the roll supported in fixed bearings, of a second roll, a movable bearing for the latter roll, a spring tending to carry the latter roll toward the first, and a fiy-wheel geared with the movably-supported roll, to exert a lateral thrust upon the latter.

8. The combination with a gatherer of a rotary stalk-lifter, a support upon which the lifter rotates freely under the friction of the stalks.

9. The combination with a gatherer, of a rotary conical lifter and a support upon which the lifter rotates freely under the friction of the stalks.

10. The combination with a gatherer of a rotary lifter contracted toward the outer part and mounted to turn freely under friction of the stalks on a shaft extending upward and outward from the gatherer.

11. The combination with a gatherer having gathering-chains of a rotary lifter sup ported to rotate freely under friction of the stalks.

12. The combination with the rolls of a corn-harvester, of means for producing an air-blast and for directing it against the stalks of corn adjacent to the point where it is engaged by the rolls.

13. The combination with the rolls of a corn-harvester of means for producing an airblast and for directin the same at different points against the sta ks of corn and toward the rolls.

14. The combination witha corn-harvester having a stripping device, of means for producing an air-blast and for directing it against the stalks of corn adjacent to the point where it is engaged by the stripping device.

15. The combination with the rolls of a corn-harvester of a shaft approximately parallel to the rolls and carrying an eccentric push-bar, and means for rotating said shaft.

16. The combination with the roll K, its shaft and movable supporting-bracket, and the fly-wheel and shaft, of intermeshing gears on the fiy-wheel shaft and roll-shaft.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
